I would like to think I know the Canon lens lineup pretty well and if someone asked me I would be able to help them out with selecting a good lens for them. However, I have had a friend who got a hand-me-down Nikon DSLR (EDIT: turns out it's a Sony!) for his 21st birthday. Not sure which model he has but I am sure it is digital and probably one of the newer models maybe a few generations removed. At the moment I think he only has a 70-300mm and has asked what other lens I would suggest. He has quite a limited budget of only around £150. I have found the kit lens on eBay for £~79. I really think this might be the best thing for him. Would anyone suggest anything otherwise, is there a nice wide prime for a low price which I don't know about? Cheers!
